Verification & What Changed
What Changed — comparing this scan to your last one
A factual diff between two comparable scans of the same website — never a guess at improvement.
Short answer
What Changed compares your latest scan to your previous comparable one (same website, same scan mode) and reports factual counts: improved, resolved in report, verified, partially verified, not yet verified, cannot verify, new, and regressed.
What this means
These categories are kept deliberately distinct so nothing gets overstated: a finding disappearing from the report ("resolved in report") is not automatically the same as "verified" — verification requires an explicit acceptance check to pass, not just the issue no longer showing up.
What to do
Run a comparable rescan (same website, same scan mode) any time you want an honest before/after — the very first scan of a website always shows "first baseline / no comparable history" instead, which is expected, not an error.
